I do click on the occasional Kickstarter boardgame advertisements, but I never end up backing because we always end up playing bloodbowl anyway.
On the other hand I do subscribe to the internet part of a Danish news paper that along giving you access to articles also removes all adds for paying users. I guess that’s sort of what brave wants to do, but who wants the hassle of buying alt-coins and reporting the taxes on it?
If you save your money, then financial companies are going to want to advertise to you to use their services. If you invest, investment opportunities will want to advertise to you. If you travel, vacation destination will want you.
Assuming you don't just put your money in a box, SOMEONE is going to want you to use your money in a way that gives some of it to them.
